Going beyond NPM: meet Yarn & pnpm

Originally published by https://blog.nicco.io

You might wonder now: why? Why should I bother reading this when NPM works perfectly? Is this just another run to the latest framework? Don’t worry: there are actual reasons you might want to switch.

Speed!!… or the lack of it?

The biggest issue that plagues npm is speed. Unfortunately even with the latest version (6) npm is slow. If you ever had to delete the node_modules folder to do a clean install on a bigger project you will know what I mean. Fans start to spin, laptop gets warm and you can go read an article while npm chews on the dependencies.

Yarn to the rescue

Yarn came along in the early days and you definitely have heard about it wandering across Github. Back in the days (before npm 5 with the package-lock.json) Yarn addressed the issues with consistency by being the first to generate a lockfile (yarn.lock). This file could be checked in and the devs would have a consistent dependencies across multiple machines.

Speed

Yarn is often twice as fast as npm. It’s truly impressive and you need to see it for yourself to believe it. The CLI output is also way more human-friendly.

yarn upgrade-interactive

This is incredible . If you run yarn upgrade-interactive you get an interactive CLI where you can choose what packages to upgrade and which not. It’s a simple thing, but one you cannot live without anymore if tried it once.

yarn why

Similar to the previous command this is a very handy cli goodie. simply run yarn why some-package and yarn will tell you why it was installed, from which dependency it came from, etc.

Lack of npx

Unfortunately Yarn lacks the npx equivalent of npm, which is the only drawback I encountered while using yarn. Other than that yarn is a very fast and a solid alternative to npm.

PNPM: The underdog

I truly love this project so I might be biased. They basically implemented a thought I had a while back: reuse the same packages across your computer. Confused? Let me explain:

Have you ever measured the size of the your node_modules?

du -sh node_modules 
# --> 816M node_modules

What?! 0.8Gb for a react-native project?!

Unfortunately that is a pretty common reality and pnpm aims to solve that.

PNPM links your packages with symlinks. This means that the same version of a package only exists once on your computer. If you ever install the same package twice, it will simply symlinked to your node_modules.

On top of that it’s even faster than yarn.

So perfection is achieved? Let’s all switch to pnpm?

Unfortunately it’s not that easy. If you start a new project you can probably go with pnpm, but with existing projects I had some problems with building my apps. So it’s definitely experimental at best and should not be used without rigorous testing as it might break your app. pnpm also supports npx with pnpx.

As you can see above there is no clear winner. NPM is the most compatible of course but really falls behind in terms of speed. Yarn in my opinion is currently your best bet and fallback to npx your-command when npx is needed.

pnpm is an incredibly cool tool but is not ready yet for production. With react-native I can cause problems, but with the “normal” stacks it works very good. I will use pnpm for my personal projects from now on.

NPM vs PNPM vs Yarn - JavaScript Package Managers

As JavaScript developers, we have access to several package managers. In this guide, we compare the most popular ones: npm, yarn, and pnpm.

In modern application development, we don’t write everything from scratch. Instead, we prefer to use existing open-source packages. Each of these packages has its own maintainers and community. So, using a package in our projects gives us some advantages like faster development, access to new, regular updates, and better security than custom-created script.

It’s common that one package depends on many other packages to work correctly. Similarly, the other packages may also depend on something like lodash, but lodash itself depends on several packages as well. In other words, the nested dependencies can sometimes become so complex that they are unable to handle dependency management manually.

Here’s when a package manager is extremely useful. Package managers are tools that automatically handle the dependencies of a project.

For example, a package manager can install new — or update existing — packages with a single command. Because everything is automated, so there’s no chance for human error. As JavaScript developers, we have access to several package managers. But, in this guide, we’ll compare the three most popular ones:

NPM Install and NPM CI: In What Aspect They Differ

Nodejs web development has achieved such a huge acclamation all over the world just because of its large ecosystem of libraries known as NPM modules. It is the largest software package library in the world, with over 500,000+ packages. Each time a Command Line Interface (CLI) for npm comes as an add-on with Nodejs installation which allows developers to connect with packages locally on their machine.

The idea of npm modules had come with some technical advancement in package management like reusable components, with easy installation via an online repository, with version and dependency management.

In general,NPM is a default package manager for every Nodejs development project. Npm eases the installing and updating dependencies processes. A dependency list on npmjs even provides you with the installation command, so that you can simply copy and paste in the terminal to initiate installation procedures.

All npm users have an advantage of a new install command called “npm ci(i.e. npm continuous integration)”. These commands provide enormous improvements to both the performance and reliability of default builds for continuous integration processes. In turn, it enables a consistent and fast experience for developers using continuous integration in their workflow.

In npm install, it reads the package.json to generate a list of dependencies and uses package-lock.json to know the exact version of these dependencies to install. If the dependency is found in package-lock.jso, it will be added by npm install.

Whereas here, the npm ci (continuous integration) installs dependencies from package-lock.json directly and use up package.json just to verify that there are no mismatched versions exists. If any dependencies mismatching versions, it will show an error.
